  • Calcicole, calcicolous

    Only growing on soils with lime.  

  • Calceolate

    Calceolate

    Slippershaped, as in the lip of some orchids; In Calceolaria, partially flat, ending in a hollow hooded tip.  

  • Calceiform

    (Of 3-dimensional structures) slipper or shoe-shaped.  

  • Calcareous

    (Of soils) containing calcium in the form of chalk or lime. Of liming composition. Having the nature of lime; chalky.  

  • Calcarate

    Calcarate

    With a spur; (of stamens or anthers) with elongated sterile portions beneath the thecae and extending below the filament insertion point.  

  • Caespitose

    Caespitose

    Growing in tight groups, the bases of the individual plants touching [preferred term]. Growing in tufts, mats, or clumps. Growing in tufts like turf.

  • CaCO3

    Calcium carbonate, lime, chalk.  

  • C3, C4

    Metabolic pathways for carbon dioxide fixation; C3 plants tend to do well in areas of moderate temperatures and plentiful water with high atmospheric carbon dioxide concentration, whereas C4 plants have a competitive advantage under hot and arid conditions.
